Specification of Letters Patent.

Patented Nov. 27, 1906;

Application filed. September 29, 1905. Serial No. 280,701.

To all whom it may concern.-

Be it known that I, PHILIPP \Vrnscnmo, a citizen of the United States,residing at Salem, in the county of Columbiana and State of Ohio,havinvented certain new and useful Improvements in Compound or DuplexWind-Chests; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to pipe-organs, and more particularly to that typeemploying tubular pneumatic action, but has especial reference to thewind-chest.

It has for its object the productionof what will be hereinafter termed aduplex or compound wind-chest embodying certain peculiarities ofconstruction which greatly enhance its usefulness.

It has for a further object the employ ment of a special formof-diaphragm-valves for controlling communication between thestopchannels and their respective musical pipes.

It has for a further object the employment of a combined perforatedmembrane-packing and check-valve g arding the pipe-ducts and cooperatingwith said diaphragm-valves to automatically regulate the wind-supply toone or more pipes from either or both stopchannels in my compoundwind-chest structure. Said membrane-packing also has for its object asimilar automatic sealing of other pressure communications or joints toprevent running of the wind, andthis lastnamed feature is to be made thesubjectmatter of a separate application for Letters Patent.

In general the objectof my present invention is the production of meansor an organized arrangement of parts whereby any particular stop in theorgan may be played not only from the manual to which it properlybelongs, but also from any other manual with whichit may be connected orcoupled, so-that any stop may be used on two .manuals at the same timealone or in combination 1 with other stops or couplers, thus doublingthe capacity of the instrument.

The invention will be hereinafter described, and particularly pointedout in the claims following. Y

In the accompanying illustrations, which form part of this application,and whereon 'lar to Figs. 3

and the other a diaphragm-valve open.

diaphragm-valves occupying the same relation as that shown by Fig. 1.Fig. 4 is also a fragmentary view corresponding with Fig. 3, except thatthe valves here occupy the position illustrated byFig. 2; Fig. 5, a viewsimiand 4, except that the valves here occupy a still differentrelation. Fig.6 is a face view of one diaphragm-valve bar, the valvescomplete being shown at each end, the adjacent valves removed,displaying the compound inlet-ports, and said bar being cut back at itscenter, showing one communicating tubular valve-duct. Fig. 7 is amodification of the invention and represents a transverse sectionthrough two stop-channels, one containing a bellows-pneumatic valveclosed Fig. 8 is a similar transverse section also representing amodification of the invention wherein diaphragm-valves exclusively areemployed all shown closed.

Reference being had to the drawings and letters thereon, A indicates thetop board, and B the bottom board, of my improved wind-chest. These areof ordinary construction and require no special description further thanthe statement that they are both crossed transversely by action-groovesor windways a a, normally containing air under comparatively highpressure from a common source of supply (not'shown) by we of the usualaction-boxes, such as O D, locatcd by preference at sides of theinstrument; cated primary and secondary pneumatics b c, res ectivc v,and these in turn are each fitted wit 1 val e-stems and valves.

E indicates a valve-stemcarried by the movable member of primarypneumatics b, and d e a double valve affixed theretov alter- Withinaction-boxes C and D are lonately guarding opposite ends of a port F,

opening outof the action-boxes. Communicating with the interior of saidprimary pn'eu- I matics b are wind-tubes f, each under control 5 of themanual or pedal keys (not shown) of the organ. Similarly the secondarypneu-- matics c are equipped with valve-stems G anddouble'secondary'valves g h alternat ely' guarding 0 posite ends ofports II, also opening throug the action-box to the atmosphere'and indirect communication with the wmdways a aforesaid. These primary andsecondary Pneumatics I) care arrangedin coacting pairs correspondingin'number with also with the windways a, before mentioned,

manual and pedal keys of the instrument and comprising sixty-one inv themanuals and thirtygin the. pedal-actions as astandard' The interior ofeach secondary pneumatic c 's in constant communication with the ports Fbyway of individual channels andare thus at times brought into'directcommunication with the interior of the action-box whereinthe particularpneumatic is located.

I J represent stop-channels separated by pipe-bars K, which lattertherefore 'also. er-

form the functions of partitions running on-. gitudinally from end toend of the windchest and fitting snugly between itstop'and bottombo'ards A B. These pi e -bars are rforated at proper intervalsyinletorts" i for communicating directly with bot adjacent stop-channelsI J and are intersected above by vertical wind-outlets 7', leading tothe musical pipes, which are not shown. but

. ordinarily surmount the top board A. When economy of space is not amatter of importance, an entire set or stop of pipes '(ordina rilysixty-one for the manuals) may bep'lac ed upon a single pipe-bar K ,.inwhich. event the stop-channels I and J are arranged in simple pairs, asshown by modified Fig. if the drawings. T e preferred construction,however, is that represented by Figs. 1 and 2 and comprises astop-channel I on each side of an intermediate stop-channel J'in triplexarrangement. In this construction all pipes of one set are placed on twopipe-bars alter natelyas, for example, pipes C D 15- Fia G31 A 5, &c.,on one bar and on the other bar pipes Gt}; D}; F G A B, &c As aconseuence of this arrangement the total width of t e wind-chest isincreased slightlv, but its length is decreased one-half, channels I, ineffect, being formed of two half-sections and the capacity of theintermediate channel J doubied by means of special valve features now tobe described;

Within each intermediate stop-channelJ is a depending valve-bar M,offset from the top board A a convenient distance bymeans of block orstrip 7c, thelatter serving also as an extra closure for the channel-atthis point. Through-out their length these ,bars M are provided withdepressions or valve-pockets N, arranged'upon both sides of said bars instaggered relation. These are covered loosely by an unbroken flexiblemembraneor individual membranes 1, upon which are secured valveallets O,as shown by Fig. 6 and elsewhere. he interior of these membrane orinflatable diaphragm-valves is placed in communication with windwaysa ofthe top board byagency-of a direct duct or tubular connection m.(Clearly shown at the center of also serve to effect n -ally guardagainst runparatively high pressure, which in other constructionssometimes results .in falsifying the pipes.

ment it is apparent that the pressure in the action-boxes and windwaysand said diaphragm-valves is identical, so that the norshown by Figs. 1,2,3, 4, and 8.

compound inlet-port. L'of the pipe-bars K, over which it is adapted toclose; but interposed between said valve and" its seat is a perforatedflexible self-acting packing-membrane P, which constitutes also acheck-valve and has a highly important function to perform, as willlater appear ina statement of may be secured to the pipe-bars in theform of a continuous perforated strip, or it may take the formof-individual membranes; but in any event its perforation or windwayinust be arranged concentrically with relation to the port L, which itguards. It should be of, a diameter to slightly obstruct said port, and

or an offset-block nthereon, when such is employed, in a manner to allowof flexible action,

as best shown by Fig. 5.

Within stop-channels I are located beltion in direct communication withwindways a of. the bottom board B through theducts R, perforating thelower edge ofpipe-bars K. The bellows-pneumatics are thus keptnormallyinflated and carry upon their movable members an arm 0, bearing pallet12 for conin shown, since they can be variously modi- Fig.. 6 andbydotted lines throughout the drawings.) Said tubes or jointless pipes m vning of the wind at' these points of com-' The pallet v() of eachdiaphragm-valve aforesaid is in register with its respective operation.This self-packing membrane P should be secured to the ,face of itspipe-bar lowsneumatics Q of ordinary construc- Asa consequence of thisarrangea mal condition of the latter is inflated, as

trolling communication between channels I fied and changed without inthe least departing from the spirit of my invention as hereinafterclaimed.

The operation is as follows: Presuming that the normal position of allprimary and secondary pneumatics b c and their-correlative valves is asshown in action-box C, Fig. 1, that the airpressure.in said action-boxesis in excess of that employed in the stop-channels, that the saidaction-boxes are in communication with the interior of alldiaphragmvalves 0 by way of windways a and tubular ducts m, and that asa consequence said boxes, windways, ducts, and valve-pockets N standnormally charged with high-pressure Wind, the valve-membranes Z thusbeing inflated the pallets O affixed thereto will each serve to normallyclose its adjacent end of the compound inlet-port L of pipe-bars K.Presuming, furthermore, the windways a in bottom board B to be similarlycharged with air at the same pressure as above, also that theycommunicate with the interior of bellows-pneumatics Q, located instop-channels I, by way of ducts R at base of the pipebars, and that thecompound pipe-ports L are here normally closed by pellets p, as clearlyshown, if now pipe-wind from a wind-trunk or other source of supply isfirst admitted to any particular stop channel or channels of thewind-chest by withdrawal of the appropriate stopknob at the keyboard ofthe instrumentfor example, stop-chan nels I I, shown in Fig. 2 andthereupon a key or keys be depressed corresponding with a musical pipeor pipes located upon said charged stop-channels, the resulting actionwill be as follows: The air is first exhausted, via wind-tuhe f, fromthe particular primary' pneumatic b corresponding with the key de- Ipressed. This pneumatic thereupon collapsing unseats or opens its valve11 and simultaneously seats its opposite valve 0, establishingcommunication with and infiating'the secondary pneumatic c by pressureof air from the action-box. As the result of,this moveas shown by Fig. 2of the drawings. As a mentthe secondary-pneumatic valve 9 is seated andits opposing valve h unseated, all

further consequence pressure from one groove a of the bottom board B isexhausted through ort H to the atmosphere, collapsing all belowspneumatics Q communicating with this particular groove a, withdrawingtheir pallets p from pipe inlet-ports L and causing those pipes to'speakwhich are located upon the previously-ch rged stop-channels I, all

other pipes in co..trollable communication with the same groove (1.remaining silent from lack of pipe-wind in their channels at the time.Similarly the grooves a of to board A are controlled from the intermelate station or action box C, Fig. 1. In this figure, however, theprimary and secondary neumatics are shownin their norparticular stopmalpositions, the diaphragm-valves inflated and their pallets 0 serving toclose the adj acent end of pipe inlet-ports L, as shown by Figs. 1, 2,3, a, and 8. A reversal of the position occupied by primary andsecondary pneumatics b c,however, exhausts the interior ofdiaphragm-valves O, causing the, same to assume the position indicatedby Figs. 5 and 7. Where this occurs in stop-channels previously chargedwith pipe-wind the pipes guarded by said valves 0 obviously will speak,all other pipes not in controllable communication with the groove orgrooves a then in action remaining silent.

In the drawings the action last described may best be observed byreference to Fig. 7, wherein one stop-channel is presumed to be chargedwith,-pipe-wind, the other stop-channel exhausted, and both valvesremoved from opposite ends of the compound inlet-port L in the mannerheretofore described. Pipe-- vent through the musical pipe or pipesabove its only source of outlet. If, on the other hand, conditions arereversed and pallet p of one bellows-pneumatic Q is located in thecharged stop-channel, pallet of a diaphragmvalve in the unchargedchannel, and both pallets are removed from opposite ends of the compoundinlet-port L, the pipe-wind then following the direction of arrows asindicated by Fig. 5 of the drawings first closes communication with theuncharged channel by agency of the packing-membrane P, as stated, andthen finds vent through vertical outlet j to the pipe.

Having thus described my invention in the best form at present known tome, I do not desire to limit myself to the construction and arrangementof parts or mode of operation hereinbefore set forth, as samo'may bevariously changed and modified without in the least departing from thespirit of my invention.
